The invention relates to a shaving apparatus comprising a housing and a shaving head holder provided with at least one cutting unit comprising an external cutting member with hair-entry apertures and an internal cutting member which can be rotated with respect to the external cutting member, which shaving head holder is connected to the housing so as to be pivotable about a pivot pin, and can be pivoted from a first position, wherein the shaving head holder is in an open position with respect to the housing, against the action of a spring, to a second position wherein the shaving head holder is in a closed position with respect to the housing, and latching means are present to latch the shaving head holder in the second position on the housing or to unlatch it from the housing.
Such a shaving apparatus is known from U.S. Pat. No. 4,318,223. It is known that in order to make shaving easier the shaving head holder and/or the cutting units, also referred to as shaving heads, can be embodied so as to be slightly floating and/or tiltable with respect to the housing of the shaving apparatus which also forms the handle. By virtue thereof, the shaving surface that is formed by the outside surface of the external cutting members can follow the contours of the facial surface more readily. As a result, to shave facial surfaces that are more difficult to reach, such as under the skin, the user does not have to make many additional movements of the wrist to reach the facial surfaces with the shaving head(s). Such shaving apparatus thus follow the contours of the face. Shaving apparatus with a tiltable shaving head holder are known, for example, from U.S. Pat. No. 4,688,329 and U.S. Pat. No. 5,007,168, and shaving apparatus with tiltable cutting units are known, for example, from U.S. Pat. Nos. 3,913,225 and No. 5,625,050.
It is an object of the invention to render the shaving head holder of the shaving apparatus mentioned in the opening paragraph depressible against the action of a spring in the operating condition, using simple means.
To achieve this, the shaving apparatus in accordance with the invention is characterized in that the shaving head holder in the second position can be depressed over a small distance against the action of the spring.
In this second position, wherein the shaving head holder is in a closed position with respect to the housing, which is the normal operating position for shaving, the shaving head holder can be depressed against the action of a spring when the shaving head holder is pressed against the skin. This causes the shaving head holder to pivot about its pivot pin.
Such a shaving head holder that can he depressed against the action of a spring can be realized in an embodiment which is characterized in that the latching means comprise a latching cam situated in the housing, which latching cam can be displaced against the action of a spring from a latched position to an unlatched position of the shaving head holder and, in the second position of the shaving head holder, the latching cam hooks behind a wall portion of the shaving head holder to latch the shaving head holder onto the housing, an edge portion of the shaving head holder being situated at some distance from an opposite edge portion of the housing, the shaving head holder being pivotably depressible over the distance. In the latched state, the shaving head holder is thus locked against rotation to the open position. Preferably, the latching means are situated at the edge of the housing opposite the pivot pin.
A further embodiment of the shaving apparatus in accordance with the invention is characterized in that the housing is provided with an upright wall portion the height of which is greater than the distance over which the shaving head holder can be depressed. As a result of this measure, in the second, closed position of the shaving head holder there is no gap between opposite edge portions of the shaving head holder and the housing. It is thus ensured that cut-off hair parts remain inside the hair chamber.
These and other aspects of the invention are apparent from and will be elucidated with reference to the embodiment(s) described hereinafter.
In the drawings:
It will be clear that other latching means are also possible provided that, on the one hand, they preclude that in the second position, wherein the shaving head holder is in a closed position with respect to the housing and which is the normal operating position for shaving, the shaving head holder can pivot to the open, first position, and, on the other hand, that they enable the shaving head holder to be depressible against the action of a spring. It is for example possible to provide the operating knob 13 as a separate knob in a wall opening of the shaving head holder opposite the latching cam 11. By depressing such a knob, the latching cam 11 is pressed back and the shaving head holder is unlatched.
